The description of "first," "second," etc. in embodiments of the present utility model is for descriptive purposes only and is not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated.

Referring to fig. 1-3, the present utility model provides a spacing assembly 100. The limiting assembly 100 includes a housing 110, a first limiting member 30, a first elastic member 40, a second elastic member 50, and a second limiting member 60.

Referring to fig. 2, the housing 110 is provided with a first receiving chamber 11, first and second insertion holes 12 and 13, and a second receiving chamber 211. Along the first direction X, one end of the first accommodating cavity 11 is communicated with the first jack 12 and the second jack 13, and the opposite end is communicated with the second accommodating cavity 211. The first jack 12 and the second jack 13 are exposed from the outer surface of the housing 110. A first boss 14 is disposed in the first accommodating chamber 11 and located between the first jack 12 and the second jack 13.

In some embodiments, referring to fig. 1, the housing 110 includes a first housing 10 and a second housing 20. The first housing 10 is provided with the first accommodation chamber 11, the first insertion hole 12, and the second insertion hole 13. Specifically, the first housing 10 includes a first surface 101 and a second surface 102 that are disposed opposite to each other. The first accommodating cavity 11 is concavely formed by the first surface 101. The first insertion hole 12 and the second insertion hole 13 may penetrate the bottom wall of the first accommodating cavity 11 and the second surface 102, respectively. The second housing 20 is provided with a second accommodation chamber 211. The first housing 10 and the second housing 20 are detachably connected, for example, by pinning or snapping.

Referring to fig. 2 and 3, the first limiting member 30 includes a connecting member 31 disposed in the first accommodating chamber 11 and a second protrusion 32 connected to the connecting member 31. The second boss 32 is configured to pass through the second insertion hole 13 and protrude from the outer surface of the housing 110. Specifically, the second stud 32 protrudes from the second surface 102. The connecting piece 31 is provided with a first limit hole 33 and a second limit hole 34 which are arranged at intervals. The second limiting hole 34 is located between the first limiting hole 33 and the second boss 32. The first boss 14 is configured to be inserted into the second limiting aperture 34. Along the first direction X, the second accommodating cavity 211, the first limiting hole 33 and the first jack 12 are sequentially communicated.

The first elastic member 40 is disposed in the second limiting hole 34, and one end of the first elastic member 40 abuts against the first boss 14, and the other end abuts against a side wall of the second limiting hole 34 away from the first limiting hole 33. The first elastic member 40 is configured to drive the first limiting member 30 to move along a second direction Y perpendicular to the first direction X. The second elastic member 50 is disposed in the second accommodating cavity 211. One end of the second elastic member 50 abuts against the bottom wall of the second accommodating cavity 211, and the other end abuts against the second limiting member 60, and is used for driving the second limiting member 60 to move along the first direction X, so that the second limiting member 60 is inserted into the first limiting hole 33. The maximum diameter of the second limiting member 60 may be greater than or equal to the aperture of the first limiting hole 33, so as to prevent the second limiting member 60 from being separated from the first limiting hole 33 in a direction away from the second accommodating cavity 211. The second limiting member 60 may also be abutted against the bottom wall of the first accommodating cavity 11, so as to prevent the second limiting member 60 from being separated from the first limiting hole 33 in a direction away from the second accommodating cavity 211. When the second limiting member 60 is inserted into the first limiting hole 33, the second limiting member 60 is exposed out of the first insertion hole 12.

The working principle of the limiting assembly 100 is as follows: when the second elastic member 50 is changed from the free state to the compressed state, the elastic force provided by the deformation of the second elastic member 50 causes the second limiting member 60 to move along the first direction X, so that the second limiting member 60 is inserted into the first limiting hole 33. At this time, the first elastic member 40 is compressed, and a limited member (not shown) may be placed on the second surface 102, where the limited member is located on a side of the second boss 32 away from the first boss 14. Then, the second stopper 60 exposed at the first insertion hole 12 is pressed in the first direction X, and the second stopper 60 is disengaged from the first stopper hole 33. After the second limiting member 60 is separated from the first limiting hole 33, the connecting member 31 moves along the second direction Y under the thrust of the first elastic member 40, so that the second protruding pillar 32 moves away from the first protruding pillar 14 along the second direction Y and abuts against the limited element, thereby limiting the limited element.

According to the utility model, the second elastic member 50 is inserted into the first limiting hole 33 on the connecting member 31, so as to drive the connecting member 31 to move along the second direction Y, and the first elastic member 40 arranged in the connecting member 31 is compressed. The second limiting member 60 exposed at the first jack 12 is pressed along the first direction X, and the second limiting member 60 may be separated from the first limiting hole 33, so that the second protruding column 32 moves away from the first protruding column 14 along the second direction Y under the driving of the connecting member 31 and the first elastic member 40, and abuts against a limited element that is pre-placed on a side of the second protruding column 32 away from the first protruding column 14. Therefore, the limiting component provided by the utility model can realize limiting without perforating the limited element.

The limited element may be fixed by at least two opposite limiting assemblies 100, or may be fixed by one of the limiting assemblies 100 cooperating with a bump mounted on one side of the limiting assembly 100.

Through the structural arrangement of the first elastic member 40 and the second elastic member 50, the elastic coefficients of the first elastic member 40 and the second elastic member 50 can be adjusted, so that the limiting assembly 100 can realize limiting and simultaneously can reduce the volume.

In further embodiments, the first elastic member 40 and the second elastic member 50 may each be one of a bellows, a rubber spring, or a leaf spring. The diameter D2 of the second elastic member 50 may be smaller than or equal to the diameter D1 of the first elastic member 40.
